Question

What is the solution to this problem?


`-(5a + 6) = 2(3a + 8)`

Answer 1

`-(5a+6)=2(3a+8)\\\\-5a-6=6a+16\\\\-5a-6a=16+6\\\\-11a=22 \ \ /:(-11)\\\\\huge\boxed{a=-2}`

Answer 2

Answer: a is -2

Explanation:

`- (5a + 6) = 2(3a + 8)`

open the brackets [ distribution ] :

`- 5a - 6 = 6a + 16`

group like terms together:

`- 5a - 6a = 16 + 6 \\ - 11a = 22`

divide both sides by -11 :

`( - 11a)/( - 11) = (22)/( - 11) \\ \\ a = - 2`
